Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0038] An EEG detection device based on a power spectrum analysis algorithm, comprising an alarm device 5, a power supply device 6, an EEG signal extraction device 3, an EEG signal processing device 4, a housing 1, a wide strap 2, and an EEG signal extraction device 3 is mainly composed of a reference electrode and a test electrode 2-1. The EEG signal processing device 4 is mainly composed of an EEG signal processing module 4-1 and a power spectrum algorithm analysis system 4-2. The shell 1 is used to package the EEG signal processing Device 4, reference electrode, alarm device 5 and power supply device 6. The wide strap 2 is sewn from a double-layer loose elastic band with a smaller elastic coefficient. The wide strap 2 is used to place the test electrode. The test electrode 2- 1 fits with the left occiput, right occiput, left ear and right ear of the human body resp...

Description

technical field [0001] The invention relates to a device for detecting the state of brain electrical activity in the field of medical instruments. Background technique [0002] When people are tired and drowsy, it is difficult to concentrate. Studying while tired and drowsy will not only reduce efficiency, but also cause certain harm to the body; if you are engaged in dangerous and difficult work, it will easily cause property loss and even lose your precious life. Therefore, the method for accurately warning people's fatigue state is a field that people continue to study. At present, the methods for detecting people's fatigue and drowsiness mainly include: detecting people's physiological signals, such as electroencephalogram (EEG), electrocardiogram (ECG), electrooculogram (EOG), etc.; and subjective evaluation method (SED). The most studied are electroencephalogram (EEG) and electrocardiogram (ECG). The difficulty of the electrooculogram (EOG) lies in the selection of ...
